Yeah, at first it sounded like a wild flyer on a slow news day, but it has hardened into conventional wisdom: Bernie and Trump are the same phenomenon, driven by the same set of facts. This is precarious America fighting back against a system that outsources economic stability to market signals. There is more anti-free trade fervor at Republican meetings than at Sanders rallies.
In any trade deal, jobs are lost and jobs are gained. If you're the head negotiator, you bargain for the bundle, not one by one. So if you see your constituency as the workforce of the next 20 years, you might deliver a promising bundle. But those whose jobs you decided to let go will be inconsolable. There can be no such thing as a universally applauded trade deal.
